Guardmaster TLSZ Overview

This Guardmaster® TLSZ guard locking switch functions by locking it actuator, which prohibits the opening of a guard.
The TLSZ uses radio frequency identification, RFID, coding to detect the appropriate target.
This version of the Guardmaster TLSZ guard locking switch features OSSD outputs. These outputs are enabled only when the actuator is locked and the RF target is sensed.
This device is intended to be part of the safety-related control system of a machine. Perform a risk assessment before installation to determine whether the specifications of this device are suitable for all operational and environmental characteristics of the machine. See Specifications on page 55 certification information and ratings.
Use nonremovable screws, bolts, or nuts to mount the switch and actuators. Do not over torque the mounting hardware.
TLSZ guard locking switches are classified according to ISO 14119 as Type 4 switching devices. The RFID targets are classified as having a high level of coding.
for
Measures are to be taken to minimize the need to defeat and to manage the use and availability of spare RFID targets.

General Considerations

Actuator/Target Mounting

The TLSZ guard locking switch is designed for use on guards that are engineered to be rigid and without sag. The TLSZ uses radio frequency identification, RFID, coding to detect the appropriate target.
Figure 2 shows the correct and incorrect ways to mount the target with the
actuator.
The TLSZ must only be used with the fully flexible actuator. The replacement part number for the actuator is catalog number 440G-A27143.

1.5 mm (0.06 in.)

Allowable Approach Directions

The actuator and target must be always mounted as “close coupled” and can approach the switch in any of the three entry slot positions that are shown in
Figure 3
. Approach from the underside is not allowed, as the distance from the
target to the internal RF sensor is too far for reliable operation.

Minimum Operating Radius

When applied to hinged doors, the minimum operating distances along the length and perpendicular is shown in Figure 4

Installation Chapter 2

Manual Release

The manual release feature only applies to TLSZR (Power to Release) switch. In some cases, you must manually release the locked actuator.
Figure 6
shows the two locations from which the actuator can be manually
released.
1. Remove the T20 Torx screw.
2. To release the actuator, insert a small screwdriver or rod in the hole.
If power is applied to the switch when the actuator is released, the OSSD safety outputs turn OFF and the switch goes to a faulted state with the status indicator flashing red at 4 Hz. Power then has to be cycled to the switch to return it to an operational state.

Figure 7 on page 14 shows an optional cover that is available only for the
TLSZR (Power to Release) switch. This cover has a lever that allows you to manually unlock the actuator at any time. Rotate the lever 90° to unlock the actuator.
If power is applied to the switch when the actuator is released, the OSSD safety outputs turn OFF, and the switch goes to a faulted state with the status indicator flashing red at 4 Hz. Power is then cycled to the switch to return it to an operational state.

Pair Proximity

Guide Repositioning

If a pair of TLSZ switches are mounted too close to each other, the two RF fields could interact causing crosstalk. Cross talk results in nuisance faults.
An absolute minimum of 200 mm (8 in.) must be used to help achieve correct operation.
The restriction also applies if a TLSZ switch is mounted close to the 440G-LZ guard locking and the 440N-Z SensaGuard™ switches.
The actuator guide can be repositioned to facilitate alignment of the actuator. In steps 8…11 (Figure 8
), rotate the metal guide to allow the switch body to be
fastened flush to the mounting surface.

Steel Locking Bolts

The TLSZ is assembled in the factory with plastic pins that secure the actuator guide. The plastic pins are rated for a holding force of 1500 N (337 lb). The plastic pins must be replaced with the steel bolts to achieve a holding force of 2000 N (585 lb). Figure 9
shows how to remove the cover to replace the blue
plastic pins with steel bolts.

Actuator Clearance

Fzh = 1500 N (337 lb)
Fzh = 2000 N (450 lb)
Figure 10 shows the clearance requirements for the TLSZ. The switch must
not be used as a guard stop. You must provide a mechanical stop at least 1mm (0.04 in.) away from the actuator guide. The actuator must be inserted within 4mm (0.16 in.) or less from the actuator guide to be sure it locks.

Rockwell Automation Publication 440G-UM002A-EN-P - March 2019 15
Chapter 2 Installation
As shown in Figure 11, the TLSZ has two slotted holes to facilitate installation. The slots allow up to 8 mm (0.31 in.) of movement of the switch body to achieve the proper clearance with the actuator.
1. Use the slotted holes for initial installation.
2. After alignment with the actuator, secure the switch body in place by adding mounting hardware in the circular holes.
3. To attain the maximum holding force, replace the plastic pins with steel screws inside the cover.

OSSD Inputs

OSSD Outputs

The OSSD inputs are Safety A+ and Safety B+. These inputs can be pure 24VDC, or they can contain test pulses. The OSSD inputs allow the TLSZ switches to be connected in-series while maintaining a high level of safety performance.
The OSSD outputs are Safety A and Safety B. These outputs are 24V signals that contain test pulses. The test pulses are used to detect short circuits to 24V, to 0V and cross faults (from Safety A to Safety B). This description of the test pulses is provided for informational purposes; you cannot modify them.
Rockwell Automation Publication 440G-UM002A-EN-P - March 2019 19
Chapter 3 Wirin g
Figure 15 shows the safety output test pulses when connected to a 1K resistive
load for hardware (HW) revisions A and B, and for firmware (FW) revisions A through C. The pulses are 25 μs wide and repeat every 20 ms. The exact shape of the pulses depends on the nature of the load. The capacitive and resistive effects of the load are determined with the combination of cabling, cable routing, and connected devices.

Commissioning
Before use, the switch must first “learn” a new RFID target. This step is not done at the factory.
The switch can learn up to eight targets consecutively. Use this process if there is a potential for the target to become damaged, inoperable, or lost. When a new target is learned, the switch no longer recognizes the older target.

Preparation

Wire up the switch with at least the functionality shown in Figure 16.
• Power — connect brown wire to +24V.
• Gnd — connect blue wire to 0V.
• Lock — Leave the green wire ‘open’ when learning the first target. Connect the green wire to 24V to teach a TLSZR switch subsequent targets. The TLSZL switch ignores the Lock command during learning.
• Safety A+ and Safety B+ — connect red and yellow wires to 24V during commissioning. If 24V is not applied to the A+ and B+ inputs, then the indicator flashes green after commissioning if the switch is locked.
• Safety A and Safety B — optional, no connection required for commissioning.
• Aux — optional, no connection required for commissioning.

First Time Power-up

Learn First Target

Turn on the 24V DC power without the actuator and target.
The Status/Diagnostic indicator blinks green 3 times, pauses 2 seconds, and then blinks green 8 times. Eight is the number of times a new target can be learned. The switch continuously repeats the two-second pause followed by the eight blink sequence.
Ta b l e 6 shows the events that take place when the first target is learned. The
lock command is ignored until after the switch learns its first target, therefore, the lock command can be 24V or 0V during the first-time learning sequence.

Commissioning Errors

Power-up Self-check

During commissioning, the switch performs certain checks. If an error is detected, the Status/Diagnostic indicator reports the error. Ta b l e 8
lists the commissioning error codes. The error code is generated after the switch verifies the target. If an error code is generated, the switch must be power cycled before further learning is started.

•After installation
• After any maintenance or change of component
• If the guard is used infrequently –Less than once per month for SIL 3/PLe – Less than once per year for SIL 2/PLd
Chapter 5

Testing Procedure

ATT EN TI ON : During the functional test, confirm that there are no persons in
the danger area and that the machine startup causes no hazard.
1. Confirm that the guard door is open.
2. Connect the 24V DC power to pin 2 and ground (0V) to pin 7. The switch conducts a self-testing routine at the end of which the diagnostic indicator shows solid red.
3. Test to confirm that the machine cannot start.
4. Confirm the lock command at pin 3 is set to 0V for PTR and 24V for PTL types.
5. Test again to confirm that the machine cannot start.
6. Close the guard door and then confirm that the guard is mechanically locked and the diagnostic indicator shows solid green.
7. Test to confirm that the machine can now start.
8. Change the lock command at pin 3. Set it to 24V for PTR and 0V for PTL types.
9. Confirm the machine stops, the guard door is mechanically unlocked, and the machine cannot restart.

Application and Wiring Examples
The following application and wiring examples are intended to show how the TLSZ products can be applied. If you are the user or the designer, you may require variations to these examples in order to meet their specific requirements.

Wiring to GLP Relay

The GLP safety relay is designed to operate with PTR switches. To use a PTL switch, you must use an interposing relay on the lock command at GLP terminal 51. In the example shown in Figure 17
, the GLP allows the gate to be
unlocked when the motor is running at a Safely-limited Speed.
Figure 17 - GLP and TLSZR Schematic
Rockwell Automation Publication 440G-UM002A-EN-P - March 2019 27
Chapter 6 Application and Wiring Examples
Circuit Status as Shown
The gate is open and unlocked. The motor is off. The GLP is ready for reset. The GLP has a Logic setting of 3: (Safely-limited Speed with Logic IN OFF), a Safely-limited Speed (SLS1) setting of 5 (5 Hz) and a maximum (SLS2) speed setting of 8 (2000 Hz). The safety outputs (X14 & X24), the single wire safety output (L11), and the auxiliary output (Y32) are OFF.
IMPORTANT Start the GLP logic configuration from “0” to configure X14 and X24 for use
as safety outputs.
Starting
Close the gate and press Reset to lock the gate and turn on the GLP safety outputs. Press Start to turn the motor ON.
Safely-limited Speed

Wiring to GLT Relay

A normal production stop is performed by pressing Stop. Access through the safety gate is initiated by pressing Gate Unlock Request. The Y32 output of the GLP turns ON and commands the PowerFlex® drive to bring the motor to a safe slow speed (Preset Freq 1). When the proximity sensors detect the speed has dropped below the Safely-limited Speed (5 Hz), the gate becomes unlocked. The operator can enter the machine cell, as the motor continues to run at the safe slow speed. After you leave the cell and close the gate, press Reset to lock the gate and return the machine to production speeds.
The circuit meets the safety requirements up to Category 3, Performance Leveld in accordance with ISO 13849-1 and SIL CL 2 in accordance with IEC 62061.
The GLT safety relay is designed to operate with PTR switches. To use a PTL switch, you must use an interposing relay on the lock command at terminal 51 of the GLP.
In this example shown in Figure 18 on page 29 command to the drive to turn OFF. After eight seconds, the GLT turns off its safety outputs and unlocks the gate. The risk assessment must determine adequate time delay for the machine to achieve a safe state before unlocking the gate.

Stopping
Normal production stops are performed by pressing Stop. Access through the safety gate is initiated by pressing the Gate Unlock Request. The Y32 output of the GLP turns OFF, which commands the PowerFlex drive to bring the motor to a stop. After the configured time delay (eight seconds) expires, the GLT safety outputs turn off, and the gate becomes unlocked. After you leave the cell and close the gate, press Reset to lock the gate and return the machine to a production state.
The circuit meets the safety requirements up to Category 3, Performance Leveld in accordance with ISO 13849-1 and SIL CL 2 in accordance with IEC 62061.

Wiring to DI and EMD Relay

The TLZ can be connected to the DI and EMD safety relays. The DI monitors the safety outputs of the TLZR and the EMD enables the gate to be unlocked after a configured delay time expires.
B1 is connected to B2 to allow for retriggering. If you open and close the E-stop and press Reset before the delay expires, the EMD timer resets.
Upon initial power-up, the TLSZ must be cycled for the DI to recognize the TLSZ OSSD signals.
In the example shown in Figure 19 on page 31 shutdown. After an eight-second delay, the TLZR is allowed to be unlocked and the hazards that remain are turned OFF. A selector switch is required to maintain the gate in an unlock state. The risk assessment must determine adequate time delay for the machine to achieve a safe state before unlocking the gate.

Wiring to DG Relay

The TLSZR can be used in GuardLink® applications; the TLSZL cannot be used in GuardLink applications. The GuardLink system uses taps to connect a series of devices to one relay. The GuardLink system provides control and status information between the machine control system and the safety system.
Figure 20
shows four TLSZR switches that are connected on two GuardLink circuits from one DG relay. The DG relay can accommodate up to 32 devices on each input. The devices can be a mix of many different safety devices. When guard locking devices are included in the GuardLink system, the lock/unlock command must come from the machine control system through the 440R-ENETR module.

Wiring to CR30 Relay

The CR30 is a software configurable relay that can easily interface with the TLSZ guard locking switch. Version 10 and later of Connected Components Workbench™ software has a locking function that is useful for guard locking applications.
Figure 21
shows an example schematic. The CR30 monitors the motor running signal from the PowerFlex® 525. When the motor is not running, the safety gate can be unlocked, and the PowerFlex 525 goes to a Safe Torque Off state.
Figure 21 - CR30 Schematic
Figure 22 on page 34 shows an example CR30 configuration that works with
the schematic in Figure 21.
The TLSZR OSSD outputs drive the Safe Torque Off (STO) signals of the PF525. The STO is enabled after the gate is locked and the Reset is pressed. The PF525 STO inputs can tolerate the pulse test that is generated by the CR30 outputs.
The Lock_Ctrl_1 block controls the unlock command to the TLSZR. The unlock Stop Time delay is set to five seconds, and the ULR Latch (Unlock Request) is set to ON. When an unlock request is made, the command is issued five seconds after the motor stops running, and the unlock request is latched ON.

Wiring to 1734 POINT Guard I/O

The TLSZ can be connected to a 1734 POINT Guard I/O™. The catalog number 889D-F8NB cordset has 24-AWG wires; which allows three wires that are connected to one terminal. This wiring example shows a Power to Lock switch with a Door Status auxiliary signal. The PLC logic checks to see if the door is closed before issuing a lock command. The schematic for this example is shown in Figure 23 on page 35

Wiring to 1732 ArmorBlock

The TLSZ can be connected to a 1732ES or 1732DS ArmorBlock® module by using an 871A-TS5-DM1 field attachable connector. The 889D-F8NB cordset has 24-AWG wires that connect to one pin. An example schematic is shown in Figure 30
.
As an alternative, you can use an 871A-TS8-D1 field attachable connector at the TLSZ and a 5-wire cordset (889D-M5NC-x).

Diagnostics and Troubleshooting
Most importantly, persons who are trained in the safety of machine systems must conduct troubleshooting procedures. This training includes knowledge of all sources of energy (for example electrical, pneumatic, safety, thermal, others).
The best approach to troubleshooting the TLSZ guard locking switches is to observe the status indicator on the switch and follow the flow diagram that is shown in Figure 36 on page 44
.

Tools Needed

Required Tools
• T20 security-Torx screwdriver bit. Notice that the security Torx has a hollowed center. You need this bit to remove the cover of the TLSZ.
• Medium-sized flat screwdriver for terminal screws, to remove terminal blocks, and to configure the switches on the front face of the relays.
• Digital Multimeter (DMM) to measure signal levels and resistance.
Optional Tools
• Oscilloscope — dual or four channel storage scope to view input and output signals and to capture signals and noise transients.
• Metal paper clips — to insert into the terminals and allow connection of scope probes to terminals.

When the status indicator is OFF, the TLSZ is not connected properly to either the 24V power supply or ground.
1. Use the Torx screwdriver to remove the TLSZ cover.
2. Use a digital multi-meter (DMM) to measure the voltage at the power supply terminals (blue wire is 0V and brown wire is plus), as shown in
Figure 37 on page 45
.
The voltage must measure between 20.4V and 26.4V DC.

If 24V is present at the wiring terminals, then check that the wires are stripped and the terminal screws are tight. If the wires are okay, then replace the switch.
If 24V is not present at the terminals, then check the power supply and the wiring up to the TLSZ switch.
The status indicator flashes red at a 4-Hz rate when an inconsistency is detected with the RFID sensor. A number of scenarios can cause this fault indication.
Wrong Target
The TLSZ is configured to detect a specific target. If a non-configured target is presented to the TLSZ, the TLSZ goes into fault mode and its status indicator flashes red at 4 Hz.
To correct this condition:
1. Replace the incorrect target with a correct target.
2. Cycle the power to clear the fault.
When received from the factory, the TLSZ is not configured to detect any target. You must configure the TLSZ to detect a target. The configuration can be a one-time event, or the TLSZ can be configured to be able to learn up to eight different targets. The TLSZ can only recognize one target. If the target gets damaged, the TLSZ can be configured to learn another target, if initial configuration is set to multi-time learning, see Commissioning Errors on
page 23.

Tar ge t
Actuator

Missing Target
If the actuator is inserted into the TLSZR without the target present, the status indicator flashes red at 4 Hz.
To correct this condition:
1. Remove the actuator from the switch.
2. Cycle power to the TLSZR
3. Mount the target next to the actuator as shown in Figure 38
.
Insert the actuator/target into the switch.
Target Not Mounted Correctly
If the actuator is mounted incorrectly, the TLSZ can operate correctly, but with reduced tolerance to misalignment of the target. The status indicator intermittently goes to a fault state with the status indicator flashing red at 4 Hz.
To correct this condition:
1. Remove the actuator/target from the switch.
2. Cycle power to the TLSZ to clear the fault.
3. Mount the target next to the actuator as shown in Figure 38
4. Insert the actuator/target into the switch.

Diagnostics and Troubleshooting Chapter 7
Pair Proximity
The RF field from a neighboring switch can cause intermittent faults. Switches with similar RF technology include the TLSZ, the SensaGuard™ switches, and the 440G-LZ guard locking switches.
To correct this condition:
1. Make sure that the neighboring switches are mounted at least 200 mm (8 in.) from any edge of the TLSZ.
2. Cycle power to the TLSZ switch to clear the fault.
Mechanical Pressure on Safety Gate
If a mechanical load (pressure) is applied to the gate during unlocking, the TLSZR goes to a fault mode. The status indicator flashes green three times and then red once. It repeats this process for 10 seconds, and then the status indicator flashes red at 4 Hz. Firmware 1.003 and earlier have a 10-second limit. Firmware 1.004 attempts to lock for 10 minutes.
1. Check the allowable spacing between the TLS and mechanical gate stop.
2. Adjust the spacing to be between 1 mm (0.04 in.) and 4 mm (0.16 in.) between the actuator and the metal guide as shown in Figure 39
.
3. Cycle power to the TLSZ switch to clear the fault.
The safety gate needs a little freedom to move when locked.

Chapter 7 Diagnostics and Troubleshooting
Long Wiring
Long input wiring adds resistance and decreases the supply voltage to the switch and reduces the safety OSSD outputs. The size of the wire also makes a difference; smaller wires have higher resistance.
Figure 40
shows the typical TLSZ test pulses when connected to a resistive
load with short [2 m (6.56 ft) wiring. The test pulses are about 25 ms wide.
IMPORTANT The OSSD outputs are about 23V and the test pulses go to zero volts.
Figure 40 - TLSZ Test Pulses Into a 1K Resistive Load
In Figure 41 on page 49, a TLSZR and GSR-SI operate successfully with long wiring. The OSSD outputs drop to approximately 21V and the test pulses only drop to approximately 8V (not 0V).

Diagnostics and Troubleshooting Chapter 7
Figure 41 - Effect of 300 ohms of Wire Resistance Going Into a GSR-SI Safety Relay
Voltage Supply Dips
When you energize the TLSZ solenoid, it causes a 350 mA in-rush current on the power supply wire. If multiple TLSZ switches are energized simultaneously, the voltage supply can dip below the 20.4V voltage specification and cause the switch to go to fault mode.
Vol ta ge d ro p i s b y:
1. The number of switches being energized simultaneously,
2. The power supply wire size, and
3. The wire length.
IMPORTANT The lock/unlock command on the TLSZ is not like the older TLS1, TLS2, and
on the TLSZ (both Power to Lock and Power to Release) is a logic level signal; about 3…5 mA. The power to energize the solenoid is provided by the ‘brown’ power supply wire.
To avoid the power supply dip, it is recommended that you stagger the lock/ unlock command to successive switches by at least 170 ms.
Rapid Locking
The TLSZL Power to Lock switches cannot withstand rapid locking and unlocking. This action results in the indicator flashing red at 4 Hz. Although the TLSZR Power to Release switches are more tolerant to rapid unlocking/ locking, they can also go to a fault state with the indicator flashing red at 4 Hz.
Rockwell Automation Publication 440G-UM002A-EN-P - March 2019 49
Chapter 7 Diagnostics and Troubleshooting
It is recommended you check that the locking operation frequency is no faster than 1 Hz with 50% duty cycle (500 ms lock, 500 ms unlock).

Step 3 - Status Indicator Flashes Red at 1 Hz

This status indicates that an undetermined fault has occurred.
Cycle the power. If the switch does not recover, cycle it again. If the switch does not recover, then run a separate cable directly from the power supply to the switch. This cable can run on the floor away from any extraneous signals. You can also provide a temporary selector switch to execute the lock/unlock command.
• Case 1: Switch Operates OK. Check the routing of the cable from the power supply to the switch. Be sure of adequate separation of switch cabling to sources of electromagnetic noise, such as drives and motion systems.
• Case 2: Switch Faults. If the switch fails with the cabling on the floor (clear of all electromechanical noise), then replace the switch.
Capacitive Loading
The OSSD outputs of the TLSZ uses pulse testing to detect faults. The pulse testing is subjected to the capacitive loading of the cabling (longer cabling creates additional capacitance) and capacitance from the device to which it is connected.
Cable capacitive loading is not an intermittent issue. Once resolved, the capacitance can remain unchanged until conditions, such as cabling changes, occur.
Use an oscilloscope to measure the pulse tests. Figure 42 on page 51 typical effect; curved leading edge indicates capacitive loading.
The TLSZR can withstand a capacitive load up to 375 nF. Higher capacitance causes the OSSD outputs to turn OFF and the indicator flashes red at 1 Hz. Higher levels of capacitance can be tolerated by adding a 10K resistor from the OSSD signal to ground.

Diagnostics and Troubleshooting Chapter 7

Step 4 — Status Indicator Flashes Green at 1 Hz

Step 5 — Flashing Red and Green

When the status indicator is flashing green at 1 Hz, the switch is indicating that it is waiting for 24V to be applied to the OSSD A+ and OSSD B+ input signals.
Upon power-up, the TLSZ performs internal checks. During this time, the status indicator flashes green three times, shows solid red for about two seconds. If the OSSD A+ and OSSD B+ inputs are not connected to 24V, the status indicator then flashes green at 1 Hz.
Corrective Action:
1. If you have multiple switches that are connected in series, check the OSSD outputs of the prior switch.
a. If the prior switch is flashing green, go to then next prior switch to
determine why its OSSD outputs are OFF.
b. If the TLS is the only switch or the first switch in a series connection
of switches, check the power supply connections of OSSD A+ (red wire) and OSSD B+ (yellow wire).
The TLSZ switch was initially configured for multi-time use. The flashing red and green indicator indicates the number of configurations that can be completed, see Commissioning on page 21

Chapter 7 Diagnostics and Troubleshooting

Step 6 — Indicator Solid Red

Step 7 — Other Considerations

The solid red indicator occurs when specific faults have not been detected.
1. Try to cycle power.
2. Remove the cable and reconnect the switch to a separate cable and use the existing power supply.
• If the switch recovers, check the existing cable routing to be sure that
the switch cable is not along motor or other high–noise wiring. Also check the grounding scheme, the 0V of the switch must be very close to the safety logic device to which it interfaces.
• If the switch does not recover, proceed to step 3
3. Remove the switch from the installation and apply a bench test circuit.
• If the switch still exhibits solid red indicator, replace the switch.
• If the switch recovers, then re-examine the cable routing and the
grounding scheme.

The TLZ can be connected the 898D distribution block. The block is available with either four or eight ports. An example with eight ports is shown in
Figure 43 on page 53

1. The cable length in this example, are all 30 m (98.4 ft) long. The cable length causes a 1.5V drop in power at the switch.
2. If the power supply is set to 24V, the voltage at the terminals inside each switch is 22.5V.
Common Lock Signal
The lock/unlock command is simultaneously applied to all eight switches. Each switch has a 300 mA nominal (350 mA max) inrush current that lasts about 110 ms (see Figure 44 on page 53 unlocked at the same, the inrush current is 2.4 A. The power supply must be able to accommodate this inrush.

Figure 44 - In-rush Current on the Power Supply at the Switch
GSR Relays on Power-up
Upon power-up, the Guardmaster safety relays (GSR) input does not recognize the status of the TLSZ outputs; the IN1 indicator remains OFF. The TLSZR must be unlocked and then locked. Then the GSR relay recognizes the OSSD outputs of the TLS. This sequence only occurs on power-up and is a function of the GSR (not the TLSZ).
